Study of the pBAD promoter

We've put the AraC-pBAD promoter (BBa_I0500) in the expression vector BBa_J61002 (between EcoRI and SpeI). After overnight culture of E.coli transformed by this plamid, we diluted 1/100 and waited 2 hours. At OD=0.2, we divided the culture in 2 subcultures, one with arabinose (final 0.2%) and one without.

1 hour later, we took pictures with fluorescence microscope (triplicate):

- the first line represent subculture without arabinose induction. - the second represent subculture with 0.2% arabinose induction.

5 hours later:
